-# Convert old themes to the new format
-
-**Rofi** 1.4 can still read in and convert the old theme format. To read the old format, convert it, and dump it into a
-new file run:
-
-```bash
-rofi -config {old theme} -dump-theme > new_theme.rasi
-```
-
-This gives a very basic theme, with the colors from the old theme.
-You can preview the theme using:
-
-```bash
-rofi -theme new_theme.rasi -show run
-```
-
-> Note: support for named colors has been dropped.

-# Theme format 3.0
-
-The way rofi handled widgets has changed in the last few releases. Widgets are now
-put into containers, allowing themes to be much more flexible than before.
-To expose these new theming abilities a new theming format has been created, replacing the old one.
-It is loosely based on [css](https://en.wikipedia.org/wiki/Cascading_Style_Sheets), a format
-widely known, which allows e.g. web developers to create their own rofi themes without learning
-a new markup.
-
-This file is split up into 3 sections:
-
-1. Specification of the file format
-2. List of possible options
-3. Examples
-
-## File Format Specification
-
-### Encoding
-
-The encoding of the file is utf-8.  Both unix (`\n`) and windows (`\r\n`)
-newlines format are supported. But unix is preferred.
-
-### Comments
-
-C and C++ file comments are support.
-
-* Anything after  `// ` and before a newline is considered a comment.
-* Everything between `/*` and `*/` is a comment.
-
-Comments can be nested and the C comments can be inline.
-
-The following is valid:
-```css
-// Magic comment.
-property: /* comment */ value;
-```
-
-However this is not:
-```css
-prop/*comment*/erty: value;
-```
-
-### White space
-
-White space and newlines, like comments, are ignored by the parser.
-
-This:
-
-```css
-property: name;
-```
-
-Is identical to:
-
-```css
-     property             :
-name
-
-;
-```
-
-### File extension
-
-The preferred file extension for the new theme format is **rasi**. This is an
-abbreviation for **r**ofi **a**dvanced **s**tyle **i**nformation.
-
-### Basic Structure
-
-Each element has a section with defined properties. Properties can be inherited
-to sub-sections. Global properties can be defined in section `* { }`.
-Sub-section names begin with a hash symbol `#`.
-
-It is advised to define the *global properties section* on top of the file to 
-make inheritance of properties clearer.
-
-```
-/* Global properties section */
-* {
-    // list of properties
-}
-
-/* Element theme section. */
-#{element path} {
-    // list of properties
-}
-#{elements... } {
-    // list of properties
-}
-```
-
-#### Global properties section
-
-A theme can have one or more global properties sections (If there is more than one
-they will be merged)
-
-The global properties section denotes the defaults for each element.
-Each property of this section can be referenced with `@{identifier}`
-(See Properties section)
-
-#### Element theme section
-
-A theme can have multiple element theme sections.
-
-The element path can consist of multiple names separated by whitespace or dots.
-Each element may contain any number of letters, numbers and '-'.
-The first element should always start with a `#`.
-
-This is a valid element name:
-
-```css
-#window mainbox listview element normal.normal {
-}
-```
-
-And is identical to:
-
-```css
-#window.mainbox.listview.element normal.normal {
-}
-```
-
-Each section inherits the properties of its parents. Inherited properties
-can be overridden by defining them again in the section itself.
-So `#window mainbox` will contain all properties of `#window` and `#window
-mainbox`.
-
-In the following example:
-
-```css
-#window {
- a: 1;
- b: 2;
-}
-#window mainbox {
-    b: 4;
-    c: 8;
-}
-```
-
-The element `#window mainbox` will have the following set of properties:
-
-```css
-a: 1;
-b: 4;
-c: 8;
-```
-
-If multiple sections are defined with the same name, they are merged by the
-parser. If multiple properties with the same name are defined in one section,
-the last encountered property is used.
-
-#### Properties
-
-The properties in a section consist of:
-
-```css
-{identifier}: {value};
-```
-
-Both fields are manditory for a property.
-
-The `identifier` names the specified property. Identifiers can consist of any
-combination of numbers, letters and '-'. It must not contain any whitespace.
-The structure of the `value` defines the type of the property.
-
-The current theme format support different type:
-
- * a string.
- * an integer number.
- * a fractional number.
- * a boolean value.
- * a color.
- * text style.
- * *line style*.
- * a distance.
- * a padding.
- * a border.
- * a position.
- * a reference.
-
-Some of these types are a combination of other types.
-
-##### String
-
-* Format:  `"[:print:]+"`
-
-A string is always surrounded by quotes ('"'), between the quotes it can have any printable character.
-
-For example:
-
-```css
-font: "Awasome 12";
-```
-
-###### Integer
-
-* Format: `[-+]?[:digit:]+`
-
-An integer may contain any number.
-
-For examples:
-
-```css
-lines: 12;
-```
-
-##### Real
-
-* Format: `[-+]?[:digit:]+(\.[:digit:]+)?`
-
-A real is an integer with an optional fraction.
-
-For example:
-
-```css
-real: 3.4;
-```
-
-The following is not valid: `.3`, `3.` or scientific notation: `3.4e-3`.
-
-##### Boolean
-
-* Format: `(true|false)`
-
-Boolean value is either `true` or `false`. This is case-sensitive.
-
-
-For example:
-
-```css
-dynamic: false;
-```
-
-##### Color
-
-* Format: `#{HEX}{6}`
-* Format: `#{HEX}{8}`
-* Format: `rgb({INTEGER},{INTEGER},{INTEGER})`
-* Format: `rgba({INTEGER},{INTEGER},{INTEGER}, {REAL})`
-
-Where '{HEX}' is a hexidecimal number ('0-9a-f'). The '{INTEGER}' value can be between 0 and 255, the '{Real}' value
-between 0.0 and 1.0.
-
-The first formats specify the color as RRGGBB (R = red, G = green, B = Blue), the second adds an alpha (A) channel:
-AARRGGBB.
-
-For example:
-
-```css
-background: #FF0000;
-foreground: rgba(0,0,1, 0.5);
-```
-
-##### Text style
-
-* Format: `(bold|italic|underline|none)`
-
-Text style indicates how the text should be displayed.  None indicates no style
-should be applied.
-
-##### Line style
-
-* Format: `(dash|solid)`
-
-Indicates how a line should be drawn.
-It currently supports:
- * `dash`:  A dashed line. Where the gap is the same width as the dash.
- * `solid`: A solid line.
-
-##### Distance
-
-* Format: `{Integer}px`
-* Format: `{Real}em`
-* Format: `{Real}%`
-
-A distance can be specified in 3 different units:
- * `px`: Screen pixels.
- * `em`: Relative to text width.
- * `%`:  Percentage of the **monitor** size.
- Distances used in the horizontal direction use the monitor width. Distances in
- the vertical direction use the monitor height.
- For example:
- ```css
-    padding: 10%;
- ```
- On a full-hd (1920x1080) monitor defines a padding of 192 pixels on the left
-and right side and 108 pixels on the top and bottom.
-
-##### Padding
-
-* Format: `{Integer}`
-* Format: `{Distance}`
-* Format: `{Distance} {Distance}`
-* Format: `{Distance} {Distance} {Distance}`
-* Format: `{Distance} {Distance} {Distance} {Distance}`
-
-If no unit is set, pixels are used.
-
-The different number of fields in the formats are parsed like:
- * 1 field: `all`
- * 2 fields: `top&bottom` `left&right`
- * 3 fields: `top`, `left&right`, `bottom`
- * 4 fields: `top`, `right`, `bottom`, `left`
-
-
-###### Border
-
-* Format: `{Integer}`
-* Format: `{Distance}`
-* Format: `{Distance} {Distance}`
-* Format: `{Distance} {Distance} {Distance}`
-* Format: `{Distance} {Distance} {Distance} {Distance}`
-* Format: `{Distance} {Line style}`
-* Format: `{Distance} {Line style} {Distance} {Line style}`
-* Format: `{Distance} {Line style} {Distance} {Line style} {Distance} {Line style}`
-* Format: `{Distance} {Line style} {Distance} {Line style} {Distance} {Line style} {Distance} {Line style}`
-
-Border are identical to padding, except that each distance field has a line
-style property.
-
-###### Position
-
-* Format: `(center|east|north|west|northeast|northweast|south|southwest|southeast)`
-
-###### Reference
-
-* Format: `@{PROPERTY NAME}`
-
-A reference can point to another reference. Currently the maximum number of redirects is 20.
-A property always refers to another property. It cannot be used for a subpart of the property.
-e.g. this is not valid:
-
-```css
-highlight: bold @pink;
-```
-
-
-
-## Elements Paths
-
-Element paths exists of two parts, the first part refers to the actual widget by name.
-Some widgets have an extra state.
-
-For example:
-
-```css
-#window mainbox listview element .selected {
-}
-```
-
-Here `#window mainbox listview element` is the name of the widget, `selected` is the state of the widget.
-
-The difference between dots and spaces is purely cosmetic. These are all the same:
-```css
-#window mainbox listview element .selected {
-}
-#window.mainbox.listview.element.selected {
-}
-#window mainbox listview element selected {
-}
-```
-
-### Name
-
-The current widgets exist in **rofi**:
-
-* `#window`
-  * `#window.box`: The container holding the window.
-  * `#window.overlay`: The overlay widget.
-  * `#window.mainbox`
-     * `#window.mainbox.box`: The main vertical @box
-     * `#window.mainbox.inputbar`
-       * `#window.mainbox.inputbar.box`: The horizontal @box packing the widgets.
-       * `#window.mainbox.inputbar.case-indicator`: The case/sort indicator @textbox
-       * `#window.mainbox.inputbar.prompt`: The prompt @textbox
-       * `#window.mainbox.inputbar.entry`: The main entry @textbox
-     * `#window.mainbox.listview`
-        * `#window.mainbox.listview.box`: The listview container.
-        * `#window.mainbox.listview.scrollbar`: The listview scrollbar
-        * `#window.mainbox.listview.element`: The entries in the listview
-     * `#window.mainbox.sidebar`
-       * `#window.mainbox.sidebar.box`: The main horizontal @box packing the buttons.
-       * `#window.mainbox.sidebar.button`: The buttons @textbox for each mode.
-     * `#window.mainbox.message`
-       * `#window.mainbox.message.textbox`: The message textbox.
-       * `#window.mainbox.message.box`: The box containing the message.
-
-Or in a graphical depiction:
-
-![Structure](structure.png)
-
-### State
-
-State: State of widget
-
-Optional flag(s) indicating state.
-
-These are appended after the name or class of the widget.
-
-`#window.mainbox.sidebar.button selected.normal { }`
-
-`#window.mainbox.listview.element selected.urgent { }`
-
-Currently only the entrybox and scrollbar have states:
-
-`{visible modifier}.{state}`
-
-Where `visible modifier` can be:
- * normal: No modification.
- * selected: The entry is selected/highlighted by user.
- * alternate: The entry is at an alternating row. (uneven row)
-
-Where `state` is:
- * normal: No modification.
- * urgent: This entry is marked urgent.
- * active: This entry is marked active.
-
-These can be mixed.
-
-Example:
-```
-#name.to.textbox selected.active {
-    background: #003642;
-    foreground: #008ed4;
-}
-```
-
-Sets all selected textboxes marked active to the given foreground and background color.
-
-The scrollbar uses the `handle` state when drawing the small scrollbar handle.
-This allows the colors used for drawing the handle to be set independently.
-
-
-### Supported properties
